In the southern U.S., rollers/crimpers are used to terminate cover crops approximately 3 weeks before planting cotton when the cover crop reaches > 90% termination. When spring is wet or cold, the 3-week period is reduced to keep recommended planting dates. A 3-year experiment was initiated in Alabama to determine the effectiveness of a 4-stage roller/crimper in increasing termination rates for cereal rye compared to 2-stage and spiral rollers/crimpers in rolling 1, 2, and 3 times over rye along with a single-pass smooth roller with glyphosate application.

Abstract:

Surface distress in the form of contact fatigue is encountered in cam-roller systems. The contact fatigue appears to be initiated at micrometer-scale subsurface region. High stress is a result of the macro-scale requirement on the cam-roller motion event that produces high contact loads due to inertia of the roller and its follower link. Sliding of the roller and its impact onto the cam surface further compounds the detrimental effect of contact load. While conventionally a Hertz contact stress analysis can be used in ascertaining contact stress and maximum subsurface von Mises stress, it gene

Improving the performance of idlers is paramount to the performance of the conveyor system in various industries since belt conveyors can be many kilometers in length and consequently there are a huge number of rollers in use. The key intention of this work is the development of a light-weight composite idler roller. Critical design considerations are strength-to-weight ratio and performance. Most importantly, the design must reduce the weight of the roller as compared to standard steel rollers.

The toroidal type CVT system has simple component arrays that have three contact points between roller and each input or output disk to get the torque transmitted.

The wrap angle, tension, and friction coefficient between the roller and the transporting film are key factors for achieving greater traction force in an R2R transport system.

Abstract:

A liquid packaging machine produces liquid packaging bags from roll film by cooperatively controlling the vertical seal roller, horizontal seal roller, and cut roller. These rollers are driven separately by servomotors as a multi-axis servo mechanism. Positioning control on the moving film is essential to make bags of accurate size. To achieve accurate positioning without lowering productivity, we propose two control methods. One is a two-step velocity control of the horizontal seal roller. This method enables continuous and high speed production of bags of arbitrary size. The second is phase

Abstract:

Load-bearing capacity is critical in planetary threaded roller bearings (PTRBs). Machining errors cause uneven load distribution coefficients (LDC) among the rollers and the threaded teeth. The limited literature explores the influence of machining errors on PTRB’s load-bearing performance. A computational model that considers multiple machining errors when determining the load distribution among the rollers and the threaded teeth is proposed in this paper. The PTRB is discretized into a multi-roller spring system. Moreover, a set of nonlinear equations is established based on deformation coor

The purpose of this study is to provide a simple method for estimating the driving resistance of rubber conveyer belts. The driving resistance of a rubber belt running on the carrier roller was estimated by a resistance force acting on a roller moving on the rubber conveyer belt while the belt was fixed on an aluminum channel. Four types of conveyor belts were tested to confirm the present technique is useful for grading rubber conveyer belts from a viewpoint of energy dissipation on the carrier rollers of the conveyer system.
